Does the sealer need to be preheated? Sealing machine sealing temperature is what? Sealing machine preheating is to make the sealing temperature of the machine to reach a certain degree Celsius, so as to carry out hot pressing sealing. When we use automatic sealing machine in daily life, the preheating time can be ignored, and if the sealing machine is used for the first time, or not used for a long time, it is better to preheat first. So, does the sealing machine need to preheat? Sealing machine sealing temperature is how much?


1. Does the sealing machine need to be preheated?


Generally speaking, the first use of sealing machine equipment, or the sealing machine placed for a long time, when starting, need to be preheated and then sealed. Because the sealing machine is not used for a long time, the heating element of the sealing machine may be damp because of air humidity, and it is necessary to conduct low temperature preheating before sealing operation.


Two, sealing machine sealing temperature is how much? 1, sealing machine packaging container for polyethylene material temperature


Sealing machine packaging container is polyethylene material, because polyethylene material can not withstand high temperature, so usually the sealing temperature control should be about 170 degrees. Polyethylene is colorless, odorless and non-toxic, widely used in food packaging, is recognized as a standard material for food hygiene.


2, sealing machine packaging container for polypropylene material temperature


When sealing machine packaging container is made of polypropylene, because polypropylene material has good heat resistance, so usually the sealing temperature of polypropylene material should be controlled in 170-200 degrees. Polypropylene is a colorless translucent plastic material with high wear resistance and heat resistance.


3, sealing machine packaging container for polystyrene material temperature


Sealing machine packaging container is made of polystyrene, because polystyrene material can withstand high temperature, usually used to make disposable containers and lunch boxes that can withstand the temperature of boiling water, so under normal circumstances, the sealing temperature of polystyrene material should be regulated at about 180 degrees. Polystyrene is colorless transparent plastic material, with strong toughness, high temperature resistance and other characteristics.


4, easy to tear film material sealing temperature


Sealing machine needs to seal the tearing film material, because the tearing film material sealing temperature is low, generally speaking, the tearing film material sealing temperature in 120-180 degrees is appropriate. Easy to tear film materials are usually used in food, daily chemical, pharmaceutical packaging, such as leisure food tablets, daily chemical products mask, pharmaceutical products tablets, etc., with low cost, easy to open and so on.


5, sealing machine packaging container for polyester material temperature


Sealing machine packaging container for polyester material, polyester is a polymer compound, is a common fiber material, its sealing temperature should be regulated in 160-200 degrees is appropriate. Polyester material has heat resistance, heat insulation and other characteristics, usually polyester packaging products can be heated at high temperature in the microwave oven, oven.


Above, is for "sealing machine need preheating? What is the sealing temperature of sealing machine?" The relevant content of the introduction, I believe that you are preheating sealing machine and sealing machine


The sealing temperature also has certain understanding. We should adjust the temperature appropriately according to the packaging material, so that the sealing machine can be normally sealed during operation.
